John Allen floating down the Colorado.

"I am just back from a great trip to Arizona and a rafting trip down the Colorado River with some friends, including an experienced birder. Some of the species seen were snowy egrets, great blue herons, mallard, bufflehead, goldeneye and teal ducks, violet green swallows, yellow warblers, a peregrine falcon, and California condors (really really big). It was a fantastic trip and made all the more interesting by my new found pastime (though since I did my best work sitting on a raft with a beer in hand, I think it was still technically “bird watching” as opposed to birding).
